Given numbers are 217, 116, 102, 247

The list of prime factors of all numbers are

Prime factors of 217 are 7 x 31

Prime factors of 116 are 2 x 2 x 29

Prime factors of 102 are 2 x 3 x 17

Prime factors of 247 are 13 x 19

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 217, 116, 102, 247

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(217, 116) = 25172

GCD(217, 116) = ( 217 x 116 ) / 25172

= 217 / 116

= 217

Step2:

LCM(1, 102) = 102

GCD(1, 102) = ( 1 x 102 ) / 102

= 1 / 102

= 1

Step3:

LCM(1, 247) = 247

GCD(1, 247) = ( 1 x 247 ) / 247

= 1 / 247

= 1

So, Greatest Common Divisor of 217, 116, 102, 247 is 1
